...and Mikey in the classic 1985 film, The Goonies. Ya know, that movie about a scrappy group of best friends who just can't seem to stay out of trouble.

And Stranger Things creators, the Duffer Brothers, regret nothing. "We’re like misbehaving children," Matt Duffer told BuzzFeed News of the joke. "I was like, 'I know I’m gonna get slapped for that by the critics, but I don’t care, I have to make it.' It just presented itself, it was too easy."

"Sean loved it, he was totally game for it," Duffer continued. "He loves to talk about it, thankfully. We asked him about it all day, and the kids are big fans so they’d pester him about it all day. He’s a talker, he loves to talk."

And there are plenty of visual nods to Goonies as well. "We’ve got kids going into a cavernous area, there’s plenty of familiar Goonies imagery in there," Ross Duffer added.

Tragically, the Duffers weren't able to work in a Lord of the Rings joke. "We probably would have done it even though that would have been a bad idea," Matt Duffer said. "But it never presented itself."
